would this be appliable to an HD558?
As far as I can tell - the process is identical. The pads come off the same way, the same screws hold things together, etc. The grill mods may be different - but reviews are mixed on whether those are worth doing in the first place.
It is essentially the same thing for models HD555, HD595, HD558, and HD598. They are almost exactly alike. Sennheiser uses different colors, foam pieces, etc to classify them. At this point, the HD598 is possibly the best value out there I can think of if your looking to get one of these cans. I've modded the HD555 heavily and did a re-cable with the HD598 and the stock HD598 easily beats the HD555 in almost all areas. I've never tested the HD595 or HD558, but the modded HD555 foam mod sounds identical to the HD595 from what I've read. I can probably believe that. The modded HD555 with the soundstage, re-cable, etc done to it probably sounds similar to the HD558 stock. But a fully modded HD598 is the best value out there if your looking at these cans. They are excellent all around cans that will benefit from amping. I have just tested the M50 from Audio Technica and that phone easily beats the fully modded HD555 and probably the HD558 fully modded. Those are great cans that get the respect they deserve for being so great stock and easy to drive. But I've been reading and doing many mods to all the HD5xx series class of Sennheiser's and the HD598 fully modded is the way to go. Of course, they won't even come close to my Wooden T50RP's, but to each his own.
i opened up my 558's today and it seemed they have no outer grill(atleast it felt like it) so i didn't dare myself to actually cut it out any1 here did it to a pair of 558?
EDIT: they definitly only have one grill so this isnt really possible on a 558
NO NO NO A big no
They actually have no inner grill, ps the only difference in sound with 558 and 598 is that the 598 is brighter and more brighter I guess its because of the outer metal grill cause the drivers are very similar if not the same !
I love this!!!
Im loving this old cans....
Recently i did the foam thing and they sounded better but now theyre improved.
Music is clearer now i can tell wheres every instrument playing. I also did a perma-eq on my sound card boosting bass a bit but ill keep playing with it cuz theres another option like that not using eq.
As for the soundstage goes......im gonna play bf3 for 2 hours or so and ill let you know.
Anyway, thnx thnx headfiers
I did the foam mod to my HD 558's and I think the bass seems to be a bit more powerful, but that could also be from burning them in so I am not sure, I had no idea the foam was used as a surround reflector, Am I losing any sound quality by removing the foam? What is the purpose of it? Also I have about 60-70 hours of burn in time, how long until they are fully burned in?
thx! Done this on my HD555. Overall, this mod by cutting the plastic is better than just removing the foam thing. By just removing foam, some music become extremely amazing but some music/sound becomes terrible (it can hurt my ears). This mod doesn't hurt my ears, but I do not get extremely great sound for some very specify music I listen to that was given me by just removing the foam. So, overall, I am happy with this.
Thanks, I went ahead and did the mod now...
First impression was pretty neutral, but after a while I realized that it just sounds more open, I can't really hear any difference in frequency response, maybe the mids are a little teeny tiny bit worse, but might be placebo.
On second thought, I'm pretty satisfied, and it also looks way cooler :p sounds opener now. Oh and I almost forgot to mention that bass isn't really affected, or at least I didn't notice anything immediately.
Also, I know what you mean, my friend got the 558s and though they aren't burnt in so I shouldn't say anything, but I preferred the sound of my modded 555s, the bass on the 558 kinda kills it for me.
The sound stage should be better on the 558 but for me it sounded worse, or maybe it's just the bass that made it sound more closed, or maybe I'm just too used to my bass-lacky 555s.
